SPECIFICATION forming part of Letters Patent No. 300,967, dated June 24,1884.

Application filed December 6, 1883. (X0 model.)

To a, whom it may concern.-

Be it known that I, JOHN H. HARDING, of the city of Milwaukee, in thecounty of Milwaukee and State of WVisconsin, have invented certain newand useful Improvements in Molds; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it pertains to makeand use the same, reference being had to the accompanying drawings, andto the letters of reference marked thereon, which form a part, of thisspecification.

My invention relates to molds for casting ornamental plaques, blocks,tiles, types, &c.; and it consists, essentially, of one or more stencilsfastened together, properly backed, and provided with walls about itsupper edges to retain the liquid or plastic material to be formedtherein. Its object is a simple and inexpensive method of preparingmolds for easting new and various designs for industrial and ornamentalwork, such as tiles, plaques, signs, cornices, center-pieces, &c.

In the accompanying drawings like letters refer to the same parts ineach figure.

Figure 1 represents a plaque bearing a design arbitrarily chosen toillustrate my improved process. Figs. 2, 3, and 4 represent the stencilswhich enter into the mold for forming the plaque shown in Fig. 1. Fig. 5shows the back or bottom of the mold, and Fig. 6 is a side view of themold.

A is a plaque of any desired design, cast of plaster, cement, or anysuitable plastic material capable of being formed in molds.

B, O, and D are the stencils necessary to form the mold for casting theplaque A. The portion 1) b is cut out of the stencil and forms thelowest relief in the mold. The parts 0 0 are cut away from the stencilC, so as to form the second or next to the lowest relief, and the parts(I d are cut out of stencil D, so as to form the highest relief. Thefull lines show the parts cut out, while the dotted lines com Thestencils B, C, and D are then stuck together in the order shown in Fig.6, and the bottom or back E to the lowest stencil with varnish, glue,cement, or any suitable adhesive material. The stencils forming themold, together with the back E, may be stuck together at the outset, andthen cut as desired. I11 this way a smoother cut can be made. and moreperfect edges formed than when each stencil is cut separately. Unlikestencils used in the ordinary way, holders may be dispensed with instencils formed into my molds, and in this way the design may be castcomplete. Parts like those marked a a a in the drawings, requiringholders in ordinary stencils, are stuck to the back of the mold or tothe stencil next underneath them. Delicate tracery-such as is seen inthe veining of leaves and the folds of draperymay be produced byindenting the back of the mold or the face of the stencils, which, whenmore than one stencil is used, become a part of the back of the mold.IiVhen raised tracery is desired, the back E, or stencil formingpart ofthe back, is indented with the pattern upon its face or upper side; andwhen it is desired to depress the pattern into the cast, it is tracedwith a sharp instrument on the under side of the back E, or stencilforming part of the back. In this way the pattern is raised upon theupper side or face of the back or stencil, and is consequently depressedinto the cast.

a e 6, Fig. 5, represent such-tracings made in the back E of the mold,and 6 shows such tracing cut or pressed into the stencil G, where itserves as a back to stencil B above it. The veining of leaves may beexactly reproduced by pasting the leaf itself to the back of the mold,the outline of the leaf being first cut in a stencil, to produce itsgeneral outline in relief.

For casting type a single stencil with a back and-side walls is used.hen the letter is cast, it may be mounted upon a block of wood of therequired thickness in the same way that electrotype-plates are mounted.

By the use of a number of stencils quite complicated designs may becast,.with as many distinct augmentations of the relief as there arestencils used to form the mold.

To provide against the east sticking in the mold, the stencil orstencils forming the same should have their edges beveled upwardandoutward. Besides, a better finish is thereby given to the cast.

In the manufacture of my improved molds for all ordinary purposes Iprefer to use oiled stencil-paper, although other materials may I 3. Themethod herein described of casting 20 be used Without departing from theprinciple of my invention.

Avariety of 1'naterials-such as wood, glass, tin, &c.may be used for theback E, which may be carved, scratched, or etched for more elaborate andfinished designs.

Having thus described myinvention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A mold composed of one or more stencils cemented together, andprovided with a back, E, secured thereto, substantially as and for thepurposes set forth.

2. A mold composed of one or more stencils stuck together, and providedwith a back, E, to which is applied an etched, engraved, or embossedpattern, substantially as and for the purposes set forth.

ornamental and industrial designs by the use of molds composed of one ormore stencils and a back, E, all cemented together, substantially as andfor the purposes set forth.

4. A moldfor casting designs in plaster or any like plastic material,composed of stencils cemented together, and provided with back E andWall F, substantially as and for the purposes set forth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

JOHN H. HARDING.
